Astronomers Detect Mysterious Radio Signals Coming From Outside Our Galaxy (sciencealert.com)

This week the New York Post reported on "powerful radio signals which have been detected repeatedly in the same exact location in space," generating as much energy as the sun does in a whole day, in "the only known instance in which these signals have been found twice in the same location in space." Slashdot reader schwit1 quotes Science Alert: Back in March, scientists detected 10 powerful bursts of radio signals coming from the same location in space. And now researchers have just picked up six more of the signals seemingly emanating from the same region, far beyond our Milky Way... Currently, the leading hypothesis for the source of the Milky Way's FRB is the cataclysmic collision of two neutron stars, which forms a black hole. The idea is that as this collision happens, huge amounts of short-lived radio energy are blasted out into space. But the repeating nature of these distant signals, all coming from the same place, suggest that can't be the case... the most likely hypothesis at the moment for these outer-galactic FRB is that they're coming from an exotic object such as a young neutron star, that's rotating with enough power to regularly emit the extremely bright pulses.
But the New York Post thinks it's aliens.

    Public imagination is a fickle thing often focused on the here and now. The great thing about FRB is that they are truly mysterious at the moment and a little over excitement is forgivable because science is often thought of as threatening or boring. Politicians are driven by the imperative to put bread on the tables of their voters and science often loses out because of it because it does not make money directly and it poses irritating questions such as climate change. So I say FRB being posed as something fantastic is not necessarily a bad thing. No doubt they are the boring result of some mechanistic behavior of the universe but just the idea of them being something more important knocks on the door of peoples imagination. It sells the story of why we do science at all, it is all about human curiosity which is a defining human quality. We are curious. The big questions in science are already literally fantastic and the answers we already have are beyond imagination. If you put up a big gravestone to the human race I think it might show the most significant progress in the area of scientific understanding. Fair enough we have encoded effective social progress in religious systems for living but the real hard work I think has been in the imagination that can comprehend outside common experience. If you insist that humans require a second party for meaning - a god - then it would seem a trivial existence not to investigate what they have created. FRB's are cool and I want to know what they are.

    Jesus never existed.

    There are absolutely no contemporaneous accounts that speak of Jesus. Not a single one. As far as the historical record is concerned he just did not exist. There's not a single carving, sculpture, poem, painting, drawing or mention of him from the time in which he supposedly lived.

    There is not a single mention in him in military records or dispatches back to Rome (and surely anyone who could command huge gatherings of people in a potentially disruptive province should be of interest). He is not mentioned in the records of Herod’s court nor is he mentioned in the records of the Temple or by any Priests. Surely if he was believed by some to be a prophet and others to be a false prophet some mention of the ruckus he was causing in Judean civic and religious society should have been recorded. Some people like to point to the supposed letters of Pontius Pilate as evidence of Jesus’ life but these were a work of fiction.

    Jesus is a composite figure assembled from many, many previous myths that all feature the same story line:

    Horus was one of the many Egyptian Gods (3100 B.C.)
    He had 12 disciples.
    One was born of a virgin in a cave.
    Like Jesus, his birth was announced via a star.
    And three wise men showed up!
    He was baptized when he was 30 by Anup the Baptizer.
    He rose a guy from the dead and walked on water.
    Lastly, he was crucified, buried like Jesus in a tomb, and resurrected.

    Buddha, (563 B.C.)
    Healed the sick
    Walked on water.
    Fed 500 men from one basket of cakes.
    Taught a lot of the same things Jesus taught, including equality for all.
    He spent three days in jail.
    Was resurrected when he died.

    Mithra, an ancient Zoroastrian deity with similarities to Jesus (2000 B.C.)
    Virginal birth on December 25th.
    Swaddled and laid in a manger.
    Tended by shepherds in the manger.
    He had 12 companions (or disciples).
    Performed miracles.
    Gave his own life to save the world.
    Dead for three days, then resurrected.
    Called “the Way, the Truth and the Light.”
    Has his own version of a Eucharistic-style “Lord’s supper.”

    Krishna, (around 3000 B.C.)
    A Hindu God.
    Born after his mom was impregnated by a God.
    Angels, wise men, and shepherds were at his birth.
    Guess what gifts they gave him? Gold, frankincense, and myrrh.
    A jealous bad guy ordered the slaughter of all newborns, just as happened with Jesus.

    My guess is it's a precessing pulsar with an offset magnetic field. Pulsars are well known to produce repeating pulses as their magnetic poles rotate in and out of view. To see the pulses requires they cross our field of view, meaning a specific alignment of the rotation axis vs location of the magnetic pole (which don't have to be the same). If there is a second body near the pulsar, with an orbit offset from the equator, it would cause the rotation axis to precess, just like the Earth's does due to the Moon and Sun. Therefore the alignment of the magnetic pole would move in and out of view, and we only see pulses on the rare occasions they line up just right.

    This guess would be defeated if the pulses look nothing like normal ones from pulsars, and confirmed if enough data is collected to detect the orbital motion of a second body.

    Flavius Josephus wrote about Jesus twice in 93.

    1) First off, it was 60 years after his death, so he could not have seen or known Jesus personally.

    2) Even worse, the writings by Josephus are now widely recognized as fake, that is, they're forgeries:

    http://www.richardcarrier.info...:
    In the TF, both grammatically and thematically, the] responsibility for the death of Jesus lies with Josephus’s fellow-countrymen, the Jews, not with the Romans, and in this too the Testimonium is hard to reconcile with Josephus’s denunciation of Pilate’s crimes against the Jews. The Josephus of the Testimonium is represented as aligning himself with the Christians (versus the Jews) and admitting that the blame for the crucifixion of Jesus the Messiah lies with the Jews; it need hardly be said that such an admission on Josephus’s part is inconceivable.

    Wikipedia:
    Many Christian apologists cite Josephus to attempt to argue that even the "pagan"/Jewish/etc. Josephus acknowledged Jesus as a savior/miracleworker/etc., and that one should therefore believe in Jesus' divinity. However, citing Josephus as a source on Jesus argument has numerous flaws. For some reason these facts almost always come as a surprise to Christians who cite him. It's almost as if they just look up quotes without any understanding of what constitutes valid sources for determining historical events.

    In Book 18, Chapter 3, Paragraph 3 of the Antiquities of the Jews (written ca. 93-94 CE), Josephus writes (Whiston’s translation):[2][3]
    Now, there was about this time, Jesus, a wise man, if it be lawful to call him a man, for he was a doer of wonderful works — a teacher of such men as receive the truth with pleasure. He drew over him both many of the Jews, and many of the Gentiles. He was [the] Christ; and when Pilate, at the suggestion of the principal man amongst us, had condemned him to the cross, those that loved him at the first did not forsake him, for he appeared to them alive again the third day, as the divine prophets had foretold these and ten thousand other wonderful things concerning him; and the tribe of Christians, so named from him, are not extinct to this day.

    Is the Testimonium Flavianum authentic? There are several reasons to think not:

    Scholarly consensus: Most scholars admit that at least some parts, if not all, of this paragraph cannot be authentic,[4][5] and some are convinced that the entire paragraph is an interpolation inserted by Christians at a later time.[6][7] Even Christian scholars consider the paragraph to be an overenthusiastic forgery,[8][9][10] and even the Catholic Encyclopedia concurs.[11]

    Context: This paragraph breaks the flow of the chapter. Book 18 (“Containing the interval of 32 years from the banishment of Archelus to the departure from Babylon”) starts with the Roman taxation under Cyrenius in 6 CE and discusses various Jewish sects at the time, including the Essenes and a sect of Judas the Galilean, to which he devotes three times more space than to Jesus; Herod’s building of various cities, the succession of priests and procurators, and so on. Chapter 3 starts with sedition against Pilate, who planned to slaughter all the Jews but changed his mind. Pilate then used sacred money to supply water to Jerusalem. The Jews protested; Pilate sent spies into Jewish ranks with concealed weapons, and there was a great massacre. Then in the middle of all these troubles comes the curiously quiet paragraph about Jesus, followed immediately by: “And about the same time another terrible misfortune confounded the Jews ...” Josephus would not have thought the Christian story to be “another terrible misfortune.” It is only a Christian (someone like Eusebius) who might have considered Jesus to be a Jewish tragedy. Paragraph three can be lift

    The reality is that there isn't really a way to CONFIRM the existence of Jesus after 2000 years,

    Many people would find this a revelation! They regard Jesus as a real historical figure like the prophets Mohammed or John Smith.
    They think Jesus is as real a Julius Caesar or Socrates, but it turns out to be a story that may or may not be based on a real person.

    The Jesus we know is from stories written well after his death by people who never met him. How many Christians wrongly think the gospels were written by the apostles? The stories were circulated verbally for decades before being written down in something like their current form.

    The oldest books in the new testament are by St Paul (who wrote about half of the letters that are traditionally ascribed to him), who also never met Jesus. He is the main source of the Jesus character, and we have no way of knowing how accurate Paul was, how much of his version is invention. But there are certainly many similarities between Paul's Jesus, and previous figures of legend. At the least, Jesus of Nazareth is a composite character.
